5. Loosen the cap for the coolant recovery tank
slowly in order to relieve any pressure. Remove
the cap for the coolant recovery tank.
6. Pour Extended Life Coolant (ELC) into the
coolant recovery tank until the coolant reaches
the “COLD FULL” mark. DO NOT fill the coolant
recovery tank above the “COLD FULL” mark.
7. Clean the cap for the coolant recovery tank.
Install the cap for the coolant recovery tank.
8. Start the engine. Inspect the cooling system for
leaks and for proper operating temperature.
Engines that are NOT Equipped with a
Coolant Recovery Tank
NOTICE
Fill the cooling system no faster than 19 L (5 US gal)
per minute to avoid air locks.
1. Fill the cooling system with Extended Life Coolant
(ELC). Refer to the Operation and Maintenance
Manual, “Cooling System Specifications” topic
(Maintenance Section) for more information on
cooling system specifications. Do not install the
cooling system filler cap.
2. Place the transmission in neutral. Start the engine
and operate the engine at low idle. Increase the
engine rpm to 1500 rpm. Operate the engine at
1500 rpm for one minute in order to purge air
from the cavities of the engine block. Stop the
engine.
3. Check the coolant level. Maintain the coolant
level within 13 mm (.5 inch) below the bottom
of the pipe for filling. Maintain the coolant level
within 13 mm (.5 inch) to the proper level on the
sight glass (if equipped).
4. Clean the cooling system filler cap. Inspect the
gasket that is on the cooling system filler cap. If
the gasket that is on the cooling system filler cap
is damaged, discard the old cooling system filler
cap and install a new cooling system filler cap. If
the gasket that is on the cooling system filler cap
is not damaged, use a 9S-8140 Pressurizing
Pump in order to pressure test the cooling
system filler cap. The correct pressure for the
cooling system filler cap is stamped on the face
of the cooling system filler cap. If the cooling
system filler cap does not retain the correct
pressure, install a new cooling system filler cap.
5. Start the engine. Inspect the cooling system for
leaks and for proper operating temperature.

Cooling System Coolant
Extender (ELC) - Add
SMCS Code: 1352-045; 1395-081
Caterpillar Extended Life Coolant (ELC) does not
require the frequent Supplemental Coolant Additive
(SCA) additions associated with the present
conventional coolants. The Extender only needs to
be added once.
Check the cooling system only when the engine is
stopped and cool.
1. Loosen the cooling system filler cap slowly in
order to relieve pressure. Remove the cooling
system filler cap.
2. It may be necessary to drain enough coolant
from the cooling system in order to add the
Extender.
3. Add Extender according to the requirements for
your engine’s cooling system capacity. Refer to
the Operation and Maintenance Manual, “Refill
Capacities” in the Maintenance Section for the
capacity of the cooling system for your engine.
Refer to the Operation and Maintenance Manual,
“Cooling System Specifications” information for
the Caterpillar ELC Extender additions.
4. Clean the cooling system filler cap. Inspect the
cooling system filler cap gaskets. Replace the
cooling system filler cap if the cooling system
filler cap gaskets are damaged. Install the
cooling system filler cap.
